Research

We provide access to mass spectrometry and gel based proteomics for identification and quantitation of proteins and their posttranslational modifications (PTM). We have state-of-the-art equipment, including an Orbitrap Fusion instrument.

Our workflows for relative protein quantitation are based on DIGE, label-free, SILAC and TMT approaches. We can also help investigators identify and quantify protein posttranslational modifications, including phosphorylation, nitrosylation, acetylation, ubiquitination, succinylation, etc. We provide training in proper sample preparation and lead the researchers through mass spectrometric analysis to data searching and interpretation. Users have access to a variety of proteomics software platforms (Mascot, Proteome Discoverer, Sequest, Scaffold) for re-searching the data or viewing the results.

In addition to helping the NHLBI investigators, we develop new approaches for PTM characterization and absolute protein quantitation.

We have state-of-the-art equipment, including the following mass spectrometers:
